  • Patent number: 7282836
    Abstract: The invention includes a D33 mode piezoelectric actuator region, including electrodes of differing length to produce a bending motion. The invention also includes a piezoelectric actuator containing a first piezoelectric actuator region coupled to a second piezoelectric actuator region, which may be separated by the ceramic material. Applying a first potential difference between electrodes generates a first bending of the piezoelectric actuator region. Applying the negative first potential difference generates the complement first bending for the piezoelectric actuator. The piezoelectric actuator region may be used to radially move a coupled transducer by the first bending. The piezoelectric actuator may be used to radially move a coupled transducer by the first bending and/or its complement. The invention includes the methods of making the piezoelectric actuator region and the piezoelectric actuator, and their products.
